Cp of a gas at its critical temperature and pressure Equals 0.24 kcal/kmol °K Becomes infinity Becomes zero Equals 1 kcal/kmol °K TRUE ANSWER : ? YOUR ANSWER : ?
On a P-V diagram of an ideal gas, suppose a reversible adiabatic line intersects a reversible isothermal line at point A. Then at a point A, the slope of the reversible adiabatic line (∂P/∂V)S and the slope of the reversible isothermal line (∂P/∂V)T are related as (where, y = Cp/Cv) ) (∂P/∂V)S = [(∂P/∂V)T]Y (∂P/∂V)S = y(∂P/∂V)T (∂P/∂V)S = (∂P/∂V)T (∂P/∂V)S = 1/y(∂P/∂V)T TRUE ANSWER : ?
